Hi everyone ,We are using our custom bootloader firmware to update our main firmware.To do that we set a flag at a specific location at RAM and reset the MCU.The flag size is 1 byte.At the bootloader firmware read the data from RAM and if this data m...
Hello, I am using nucleo stm32f429zi. I want to add MCP3304 SPI with my controller. It works properly, but my spi clock is 1.325MHz, which means my channel sample rate will be 1.325MHz/21=63095Hz (sample rate for 4 differential channels). so each ch...
Is there any 32-bit ST microcontroller that contain WiFi in it?
DS12110 Rev 5, notes for Figure 40. says it should be in Table 85 but it isn't. Rain and Cadc are in the Table 85.
i want to execute few lines of code on both edge of input pin i know about interrupt but what is external event ?
Dear Members,How can I save date and time setting on STM32L152RE ?Everytime I have reset, it's initialized to the value on init code, how can I the value after power off ?I put a battery on VBAT , it doesn't help,Thanks
Question regarding an implementation of RS485 on an STM32.The application note (reference guide) refers to 4 bits stored in the USART_CR2 register which can be used as an address comparison to aid with waking only when required.“Address mark detectio...
In the ADC chapter, DMA_SxNTR register is mentioned. There's no such register, it's DMA_SxNDTR.This goes across many RMs - I've checked several 'F4 and 'F7 (using simple text search) and all of them contained it.JW
Hi folks,currently I am working on an communication with a sensor via QuadSpi using the STM32F446 controller. The QuadSpi Bank1 was chosen, but unfortunately the hardware designer did not connect the Chip Select signal (CS) to the pin that correspon...
